CHARA/SPICA: The six-telescope visible combiner and near-infrared fringe tracker for the CHARA Array
D. Mourard, P. Bério, C. Bailet +43
The suite called Stellar Parameters and Images with a Cophased Array (SPICA) has two interferometric instruments installed at the focus of the CHARA Array located at Mount Wilson,…
CHARA/SPICA: a 6-telescope visible instrument for the CHARA Array
Denis Mourard, Philippe Berio, Cyril Pannetier +25
With a possible angular resolution down to 0.1-0.2 millisecond of arc using the 330 m baselines and the access to the 600-900 nm spectral domain, the CHARA Array is ideally configu…
SPICA-FT: The new fringe tracker of the CHARA array
Cyril Pannetier, Philippe Berio, Denis Mourard +11
SPICA-FT is part of the CHARA/SPICA instrument which combines a visible 6T fibered instrument (SPICAVIS) with a H-band 6T fringe sensor. SPICA-FT is a pairwise ABCD integrated opti…
Compensation of differential dispersion: application to multiband stellar interferometry
Cyril Pannetier, Denis Mourard, Frédéric Cassaing +5
With the aim of pushing the limiting magnitude of interferometric instruments, the need for wide-band detection channels and for a coordinated operation of different instruments ha…
Progress of the CHARA/SPICA project
C. Pannetier, D. Mourard, P. Berio +22
CHARA/SPICA (Stellar Parameters and Images with a Cophased Array) is currently being developed at Observatoire de la Côte d'Azur. It will be installed at the visible focus of the C…
Hartmann vs. reverse Hartmann test: a Fourier optics point of view
Francois Henault, Cyril Pannetier
The Shack-Hartmann Wavefront Sensor (WFS) is well-known in the fields of optical metrology, wavefront sensing in astronomy, and ophthalmologic control applications. The purpose of…
Low Wind Effect on VLT/SPHERE : impact, mitigation strategy, and results
Julien Milli, Markus Kasper, Pierre Bourget +14
The low wind effect is a phenomenon disturbing the phase of the wavefront in the pupil of a large telescope obstructed by spiders, in the absence of wind. It can be explained by th…
